I find it interesting that you talked about nutrition supplements for athletes. I am very close to launching such a product for enhancing aerobic exercise performance in women (ie. improved times in a 3 mile run).. The product contains no stimulants or exotic herbs. In fact three of the five ingredients are well known minerals, but in forms not found in most multi-vitamin-mineral supplements. The research behind the product comes from me. The credibility behind the research is that I am a professor of human nutrition with over 100 research papers. Now, the trick will be to use my connections and credibility in a business savvy way.
Link building is yet another factor that is linked to both content marketing and keyword usage. Link building can be done in various ways. You can make guest posts in few websites that have high DA and add a link to your site. This is known as backlinks. Usually guest posts come for free. You can also get paid backlinks, in which a paid article with a link to your site is posted in other sites, in lieu of money. Another option is to create internal links, where one page is linked with the other. This is a great tactic to increase on-site time, traffic and conversion rate. Some tips to remember in link building:
There are several types of affiliate programs. Most will pay you a flat rate or percentage of the sale you make (pay-per-sale). Another common type is when you're paid per action or lead. For example, if you refer someone who signs up for businesses free trial, the business pays you for the sign-up. Although not seen as often anymore, some will pay you per click (this is seen most in contextual ad programs such as Google Adsense) or per impression (each time the ad is loaded on your website).
Take good pictures. Some of the options below don’t require you to actually take the picture and sell the product, but for the ones that do, make sure you take a clear picture that makes your product stand out from the others. If you’re going to be taking a lot of pictures, set up a small “studio-like” area in your home with a backdrop and proper lighting to really make your pictures come across as professional. And of course, you’ll want a good camera too.
The frequency and method of payment vary as well. Most programs pay their affiliates monthly, although a few pay more frequently. Some require that affiliate earnings reach a specific threshold, which can be as low as $25 or as high as $100. Some programs don't have a threshold. There are programs that pay through direct deposit into your bank, but a vast number pay through PayPal.
Quality content is more likely to get shared. By staying away from creating "thin" content and focusing more on content that cites sources, is lengthy and it reaches unique insights, you'll be able to gain Google's trust over time. Remember, this happens as a component of time. Google knows you can't just go out there and create massive amounts of content in a few days. If you try to spin content or duplicate it in any fashion, you'll suffer a Google penalty and your visibility will be stifled.
Thanks for a this timely article. If I understand it correctly, are you saying that we would better be off looking at market data in our niche and make an article of that for influencers to share rather than actionable tips that the target clients would be interested in? Shouldn’t there be a double strategy – articles for the influencers to share and articles for the users to enjoy?
In my experience, a lot of people are more open about sharing traffic stats then you would think. You see this not just in interviews but if you peruse through the archived articles on a blog, there’s a good chance you’ll stumble upon a “blog in review” or “traffic report” post. With those stats, you can start to figure out how much traffic the site is getting today.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
I never really knew how Google Adwords was working for me until I began tracking conversions with LeadDyno. While I always used the conversion tracking pixel that Google provides, I always found it to be imperfect. That’s because I want to measure specific $$$ amounts and sales… while Google is only able to tell me if someone made it to a certain page. Like a sign up, or “thank you” page. That’s a good start – but I need more! Specifically, I need to know what somebody bought and/or signed up for… how much they purchased… and how long they stayed with us afterwards. This is easy to do with LeadDyno. All you need to do is create a new marketing campaign tracking link – as use this link as the Target URL within Adwords. Or, if you’re advertising on Facebook, just make sure the link that you provide Facebook with is a campaign tracking link from LeadDyno. Don’t just give Facebook the link to your homepage – give them this link instead. It’s pretty much the same thing as using an affiliate link to track the effectiveness of a specific marketing campaign. Because LeadDyno is already plugged into your website – and most importantly, your E-Commerce provider – you’ll have visibility into the entire sales funnel that was generated as a result of each specific advertising campaign you are tracking. I’ve been doing online marketing for the past decade, and I can tell you this is huge. It allows me to test campaigns quickly and easily. I’m able to let our winners run, and cut our losers short.
